Hello! I'm very new to chickens (we have four 2-week old chicks all doing wonderfully so far), and I'm trying to learn all I can. We live on the edge of a very small town in rural WI. There are farm fields behind our house, and woods & lakes beyond the fields. We'd love to let our girls free-range a bit when they're older, but I'm worried about hawks. We have several of them behind our house, and they frequently come to our backyard. I know we also have fox & raccoons, but they seem to only be out at night. I am torn between wanting the girls to have lots of room to roam and be happy, and wanting to keep them safe. We are building a run of appx 48 sq ft. Any advice for a new chicken mom?
